Strap for Constellation Co-Axial 38 White Gold / Diamond / Black

The lug width of this model is 20mm. This dimension is determined by the proportions of the 38mm case and the integrated lugs. To verify it with precision, use a caliper to measure the distance between the two spring bars that support the strap, perpendicular to the case.

African or American alligator is the noblest choice for formal elegance, as its fine grain does not visually compete with the diamonds on the dial. Vegetable-tanned calf develops a golden patina over time, creating contrast with the white gold. For daily practicality, Fluoroelastomer rubber maintains sophistication, while burgundy shell cordovan represents the bold and luxurious solution.

Use a spring bar tool to gently extract the spring bars from the lugs. Position the tool parallel to the case, from the inside of the lug, and push outward until the spring bar disengages. Repeat on both sides, then insert the new strap by aligning the holes and pressing until it clicks into place. If you prefer to avoid risks, contact the Casati Milano atelier to ensure precision and case protection.

A premium quality leather strap, such as those offered by milanostraps.it, has an estimated lifespan of 3-5 years with daily wear, if subjected to proper maintenance. Factors that influence longevity: exposure to direct sunlight (ages the leather), frequent contact with water (swells the fibers), and excessive heat. An alligator or shell cordovan strap tends to last longer than standard calf leather, thanks to the denser fiber structure.
